Excellent post RI! Man, looking at your graphic gets me tired!
A couple of things to add, you can take the ticket to any POA office in Ontario. They'll photocopy your ticket and then stamp it and give it back to you. If possible, can you post a photo of your ticket here (blanking out the personal details)? I'm interested in the fine amount box at the bottom of the ticket to see if it's completed correctly.
Request disclosure specifically asking for a copy of the original photographs, a clear indicator of the timing of the photographs and the speed of your vehicle. Also ask for a clear picture of the superimposed numbers.
Ask for evidence that the camera was working properly (maintenance logs, etc.) And ask for the operator's manual for the camera so that you can better understand how it works.
If you don't get any of this, you can apply for a stay based on improper disclosure.
Also if the speed of your vehicle is slow, it's an indicator that you stopped and began to turn. If the speed is too fast, it may be an indicator that the sensor was picking up another vehicle (which might be in the picture!)
The important lesson here is that the photographs paint only one side of the story. There's another side that you will bring out at trial.
